Digital load cells by BoltSafe are specially designed for measuring and monitoring bolt load. They are able to do this in bolted constructions, both during assembly and over time. This knowledge gives better control over the construction, enhances safety and makes joints more dependable. The BoltSafe digital load cell is placed on the non-driven side of a bolted connection, preferably under a nut. When the bolt is being tightened, forces are applied to it. This results in minor deformations of the stainless steel washer. Our digital sensors are able to measure the change in electrical resistance caused by these deformations. This is the data we use to determine the (bolt) load very precisely at any given moment.
Our digital load cells can be used for many different purposes, examples are for Structural Health Monitoring and in temporary constructions. Here they will keep the constructions from collapsing by measuring the load on critical elements. We offer load cells for continuous and periodic monitoring, both in a regular version and a stronger version that withstands 15% more load while keeping the same compact dimensions. BoltSafe sensors send out only digital signals and are therefore the perfect example of a digital load cell.
